In recent years, technological advancements have revolutionized the way we interact with our devices, especially smartphones. One of the most notable innovations in this regard is the introduction of fingerprint sensors. Traditionally, these sensors were placed on the front or back of the phone, occupying a dedicated space. However, a new generation of fingerprint sensors has emerged, which are embedded directly under the screen. This revolutionary technology, known as the fingerprint sensor under the screen, allows for a seamless and more immersive user experience. In this article, we will explore what exactly the fingerprint sensor under the screen is, how it works, its advantages, and its impact on our daily lives.
When the trend of overflow screens is growing strongly, it is impossible to equip a fingerprint sensor on the front and the solution to bring the fingerprint sensor into the screen is considered a good solution. best.
What is the fingerprint sensor under the screen?
As its name implies, the fingerprint sensor under the screen is a fingerprint sensor cluster located below the display screen layer, which can recognize the user’s fingerprint without affecting the display’s visibility. image.
Specifically, when the sensor detects a finger, the smartphone screen will shine (or emit ultrasonic waves) on the finger and the sensor will scan the fingerprint on that finger. Next, an image data comparator will confirm the scanned image and unlock the screen for you. This sensor can be placed anywhere on the screen.
Types of fingerprint sensors under the screen
Currently, there are two popular types of fingerprint sensors under the screen:
- Optical fingerprint sensor (using light to capture fingerprints).
- Ultrasonic fingerprint sensor (using ultrasonic waves emitted to record fingerprints).
Advantages of in-display fingerprint sensor
As mentioned above, equipping a fingerprint sensor inside the screen will allow manufacturers to bring a real screen experience instead of sacrificing a part for the fingerprint sensor.
The fingerprint sensor under the screen can be integrated anywhere on the screen so you will not be fixed where the sensor is located.
Disadvantages of in-display fingerprint sensor
Although the in-display fingerprint sensor technology is developing very quickly, the recognition speed is still not comparable to the traditional fingerprint sensor.
The fingerprint sensor under the screen can only be integrated on the OLED screen, so the cost will also increase, so currently only high-end or high-end smartphones are equipped with this technology.
Using the fingerprint sensor under the screen makes users have to consider when applying screen protectors because it is possible that some types of stickers will not be compatible with this technology.
Smartphones are equipped with fingerprint sensors under the screen
Optical fingerprint sensor: Can be mentioned as Vivo V11, Xiaomi Mi 9 or Samsung Galaxy A50…
Ultrasonic fingerprint sensor: This technology first appeared on the Samsung Galaxy S10 and S10+ duo from Samsung.
Hopefully the article will give you an overview of fast charging technology on phones. In the process of using, if you have any questions, don’t hesitate to share with Thptlaihoa.edu.vn!

In conclusion, the fingerprint sensor under the screen is a innovative technology that has made its way into modern smartphones and other electronic devices. It offers a more seamless and integrated user experience by eliminating the need for a physical fingerprint sensor on the device’s surface. By utilizing ultrasonic or optical technology, the sensor is able to accurately capture and authenticate the user’s fingerprint through the screen. This not only enhances the aesthetics of the device but also improves the security and convenience for the user. Although there may be some challenges like slower response times or reduced accuracy compared to traditional fingerprint sensors, manufacturers are constantly improving the technology to overcome these limitations. Overall, the fingerprint sensor under the screen is a promising development and is expected to become more widespread in the future, further revolutionizing the way we interact with our devices.
